Librep is a LISP dialect lying somewhere between emacs lisp, common lisp and
scheme. It drives sawfish and jade,
and can be used to serve web pages using the mod_rep
Apache module.

jsh, the original developer of librep, stopped developing
librep at
version 0.17. Christopher
Bratusek, Gnome's sawfish maintainer, has since forked librep with jsh's
blessing; the code's git repository is available at git.gnome.org/cgit/librep.
